I've specified the parameter file I used but when I try to run it, I get the error that "namd2.exe has stopped working". I'm working on Windows, and I downloaded and extracted the entire zip file for namd, so I don't think I'm missing any files.

I'm not sure why it wasn't able to open the psf file. I've loaded it in vmd and opened the dcd file on top of it at stride 10.

I had trouble with the unix version of namd choking on path names that were longer than about 135 characters. This might be a similar issue. You could try renaming or moving the file so the path length is shorter and seeing if that fixes things.
